Make TRANSPARENT windows be layered windows on win aura
This builds on jbauman's patch to plumb use_software_compositor
from here: https://codereview.chromium.org/23621054/
The motivation here is that we currently have very different
event, focus, activation paths on DWM vs. classic because of the
differences between when we use top-level windows and when we
don't. With this change, all translucent (i.e. shaped) windows
are converted to being top level (always), and are rendered by
the software compositor and are converted to layered windows for
rendering.
BUG=293218 and many other focus/activation bugs
